This is a great no frills - but quite large for what it is - apartment in an awesome building in an amazing location. Quiet at night. Close to fun. Inexpensive. The building has a gym - not like a commercial gym but it's possible to get a good "travel" workout. Has laundry with a dryer (which was important to me as I hate the way my t-shirts feel after being air-dried). Has a doorman - I felt my stuff and money was secure. The bed was comfortable (unlike most beds I've experienced in AirBnB places). AC units in both rooms with separate remotes. A small balcony.
Gael is a very gracious and accommodating host. I would love to stay there again on my subsequent visits to Bangkok.
